Hi,Hopefully you've found a toilet by now but for others who are still searching for a small one... I beleive Kohler makes one called the Rialto that they advertise as being the smallest (front to back) on the market. Also, have you considered a wall mount toilet? They are spendy (the ones I've seen are about $900 by the time you buy all the bits and have it installed), but certainly are tiny. -J
